SPECIFIGATIN forming part of Letters Patent N o. 702,075, dated une 10, 1 902.

Y. Anuman leannuty 30.1902.' serial No. 91,sso, Nomode1 .To all whom it may concern: -f f Be it .known that '1, MAXIMILIAN PIuK,-,a` citizen ofl the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Liquid-Pressure Regulators, of which the following is a specification.

This invention relates toan improved apparatus for charging fermented beverages,

l der a uniform pressure which may be accu- 1v1, Figs.. 2 and- 3. Fig. 2`is aplanwith thecover removed 5 Fig. 3, aplan of the disk ;4 and Fig. t a section on linel 4, Fig. 3, with som ofthe parts omitted'.

The letter @represents a gas-cylinder adapted to be introduced` intothe barrel or other receptacle A, that contains the beverage to be placed undergas-pressure,v Into vthe upper threaded end of cylinder a is'tted thethread;i ed sleeve b of an' annular` disk b, whichfis' placed upon the head of the barrel; The disk b is provided with an Ainlet-duct c',`con'trolledj ,by valveo and communicating with-,the inwterior of cylinder'a by mean'sof adu'ct c jof.

sleeve b. This duct c iny turn communicates with an outlet-duct .c'z' off'a nozzle d, that'is" formed upon the disk band projects into the*v central opening of said disk.l Below the noz-' Yzle d the sleeve b is closed byla'screw-,plugj b2. Within the` sleeve b' isfree to movea` valve e, Fig. l, arranged` beneath the nozzle cland adapted to close theduct c?. This valvev is connected by a yoke or arm f with an elasticdiaphragm g, made, preferablygof copper and seated upon a Iiange b3 of disk b, towhich it is soldered. The yokei f is influenced by a spring h, between which and the elasticY diaphragm is interposed'a collare', tted around the upper threaded shank f of yoke f. This shank isj guidedin. a socket jc'` of acover j,

`which is screwed to disk b, .the screw-holes lo' of the diskbeing shown in Fig. 2.

In order to regulate the tensionl of lspring 71, and consequently thegaspressure,l I provide a pair of screws Z, the heads Z' of which are countersunkin diskb. Each of the screws ary, 1902.'.

`is engaged by a nut or threaded trunnion-block `'rr`1`to"which are pivoted at 'n the outer ends of a pair of links n, the inner ends of which are connected by pivots n2 to the ends of ,spring 71. Thus it will be seen that by turn- F'ingthe screws ll the nuts m will be moved up or down, and thus the tension vofjspringh may be regulated in a simple and accurate manner.

Below the i diaphragm .g 4is 'formed' a gas- .'chamber g,'which communicates -With the interior of the barrel by aduct 0. Within this duct is arranged a check-valve p, which prevents back'pressure and which consists, prefierablyfof a perforated rubber diaphragm.

Under back pressure `the portion containing c l the perforation p' of thisdi'aphragm is forced against al plug p2, and in vthis way 'the valve isclosed.

The operationl is as follows: The liquid carl bonic acid is introduced into the cylinder a.

through ducts c c froml asuitable receptacle.

Within the cylinder ot'the liquid carbonio acid ga'siies, and the gas passes through duct Y c-v and-duct 'c2l of' nozzle dinto the gas-chamber From chamber g' the 4gas, enters the .barrel through ope'nvcheck-valvep andduct 0.

-Itlthe gas-pressure inthe bar'rel'an'd beneath diaphragm g ezi'ceeds the pressure to which the" splingfhhas beenset, the diaphragm will be lraised `against theaction'fof thespring to correspondingly raise thegvalve e against nozzle ci by'yokef. In this w'ay the supply of gas will' be correspondingly diminished or entirelycut ofsdthat'Jan even pressure is l maintained. v

What-I 'claim is v Y. In a liquid-pressure regulator,the 'combination of a nozzlewith va coacting valve, a diaf phragm connected to thevalve, a spring 1niiuencing the diaphragm, la'pair of screws,`

nuts embracing the screws, and links that` l pivotally connect the nuts with the spring,- substantially as specified.
